BEAM-SETTING PRESS- Specification of Letters Patent.

Patented April 23, 1907.

Application filed May 19,1905. Serial No. 261,270.

To all w/wm it may concern:

Be it known that I, Max SKLovsKY, a citi- Zen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented a certain new and useful Beam-Setting Press; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The subject of the present invention is a machine intended for clamping iron plowbeams while they are in heated condition so as to bring their respective parts in proper alignment and so that future bending or straightening by hand wi ll be avoided.

Heretofore the plow-beam was bent to its curved shape, and while still hot was held in place by a support, and the workman would hit one side or the other of the beam to straighten or true it up by the eye. The results obtained in this way were of course more or less unsatisfactory as they involved considerable expense and were accompanied by more or less inaccuracy.

The main function of the present machine is, first, to clamp the rear end of the beam in a fixed position, and then automatically to bring the front or clevis end of the beam to its proper relation with respect to the rear end. It will be understood that the rear end is the one to which the plow is attached and in relation to which the front end must have a particular set and exact location.

The accompanying drawings, which form a part of this specification, illustrate one preferred embodiment of my invention, which however is susceptible of various modifications and capable of embodiment in other forms. Without limiting myself, therefore, to the specific construction illustrated, the invention will hereinafter be fully described with reference to said drawings, and then particularly pointed out and defined in the claims following this description.

In said drawings: Figure 1 is a top plan view of said machine embodying my inventtion, in which the relative location of the mechanisms is fully shown. Fig. 2 is a side elevation of the same, with a plow-beam rep resented in its position in the machine. Fig. 3 is a rear elevation, showing the clampingjaws for the rear end of the beam open, and representing the cylinder and its piston for frame at the left.

operating said jaws in vertical section. Fig. 4 is a similar rear elevation, showing the said clamping-jaws closed; this view being fragmentary and omitting a part of the machine Fig. 5 is an enlarged transverse vertical section through the mechanism which sets the forward or clevis end of the beam, showing the clamping-jaws thereof open. Fig. 6 is a similar section showing the clamping-jaws closed.

A particular explanation of the illustrated construction is as follows:

A indicates a vertically disposed casing or frame at the rear end of the machine, and B denotes a horizontally arranged bed extending forward therefrom.

The clamping apparatus for the rear end of the beam is shown in rear elevation in Figs. 3 and l. 0 and D denote the clamping-jaws, shown open in Fig. 3 and closed in Fig. at. These jaws are vertically disposed, to clamp the plow-beam sidewise between them. 0 is shown as a fixed jaw, and D as a movable jaw carried by the rocker-arm E. The aw D is pivotally attached to the upper end of said rocker-arm, to permit it to come flatwise against the plow-beam when the jaws are closed. These jaws are operated by the piston or plunger F which works in the cylinder G, to which suitable motive fluid, preferably compressed air, is admitted for propelling said piston. inder is shown vertically disposed and located laterally beside the rocker-arm E, which carries the movable jaw. The pitman II of the piston is connected to the knuckle of a toggle I J, the arms or links of which are of different lengths. The longer toggle-link I has a stationary pivot or fulcrum, while the shorter toggle-link J is pivotally connected to the rocker-arm E. hen the apparatus is in the position shown in Fig. 3, the piston being at its lower position, the toggle-links are out of alignment and the jaws O and D are held open. But when compressed air is admitted to the cylinder behind the piston, the pitman lifts the knuckle of the toggle, bringing the toggle-links into alignment and thereby positively closing the jaws, to clamp the rear end of the plow-beam rigidly between them. On exhausting air from the cylinder, the piston will fall by gravity, and this is assisted by the rockerarm E, which is self-movable in the direction to open the In this case, the cyl-- jaws, its lower fulcrum or pivot being disposed to the left of the center of gravity of the rocker-arm.

The apparatus for setting and clamping the front end of the beam is carried by a frame or carriage K, which is slidably mounted on rails L, arranged longitudinally of the bed B. This permits said carriage to be moved toward the front or rear of the machine, so as to locate it at the proper distance from the foot of the beam, to adapt the mechanism to plow-beams of greater or lesser lengths. This front mechanism is shown fullyin Figs. 5 and 6. Thealignment and setting of the front end of the beam is accomplished by the (so-acting V-shaped jaws M and N, which travel vertically to and from each other. The lower jaw M is carried by a heavy piston or plunger P, which works in the cylinder 0, rigidly attached to the lower part of the carriage K. The upper jaw N is carried by a block Q. The piston P and block Q are guided in their up and down movements by the guide-frame R, which is rigid with the carriage K, and has top and bottom openings in which said piston and block are respectively fitted. The upper block Q is operated by the levers S S, which are intermedially fulcrumed on pivots attached rigidly to the frame or carriage K.

The inner ends of said levers are connectedare connected by pitmen U with the piston P. The jaws M and N are operated to close and clamp the beam by admitting motive fluid, preferably compressed air, to the cylinder 0, which forces up the piston P, thereby lifting the lower jaw, while the lever and link connection U S T simultaneously forces down the upper jaw. On exhausting the air from the cylinder 0, the piston P willfall by its own weight, thus separating the jaws. It is designed that the aws shall always travel toward and away from each other equally, that is, as the lower jaw rises the upper jaw will travel downward exactly the same distance, this being accomplished by properly pivoting the levers S. The jaws are arranged to pass or overlap each other when close together, as shown in Fig. 6, so as to restrict the opening between the V-shaped jaws and clamp the beam. The vertices of these V- shaped jaws may be suitably squared, to conform to the angular formation of the beam. By virtue of this mechanism, it is obvious that whether the plow-beam which is to be clamped between thejaws is above or below the center, or to the right or left thereof, it will be automatically drawn to an exact center, being engaged by the opposed closing V-shaped jaws, and clamped between the vertices thereof. The jaws M and N are preferably adjustably secured to the cylinder P and block Q respectively, and secured by set-screws as shown in Figs. 1, 5 and 6, to permit lateral adjustment thereof in accord.- ance with the land or lateral deflection to be given to the beam.

The compressed air or other motive fluid may be admitted to and exhausted from the cylinders G and O by any appropriate means. In Fig. 3 I have indicated diagrammatically a suitable valve V, having airsupply and ex haust pipes W and X, and supply-pipes Y and Z leading therefrom to the cylinders G and 0 respectively.

The operation is as follows. The plowbeam is first placed in position in the machine, its rear part being properly located between the laterally-movable clamp-jaws C D, and its front part extending between the vertically-movable clamp-jaws M N. The compressed air or motive fluid is first let into the cylinder G, which actuates the piston F, and through the mechanism H I J closes the clamp-jaws C D and securely clamps the rear part of the beam. The air is then let into the front cylinder 0, which actuates the piston or plunger P, thereby closing the clamp-jaws M N, which brings the front or clevis end of the beam exactly to its proper relation with respect to the rear end. WVhen the beam is properly set, the air is exhausted from the front cylinder, and then from the rear cylinder, and the entire beam is released.

In Figs. 1 and 2, B denotes a vertically disposed post and B a vertically adjustable screw or plug therein, adapted to support the beam in proper position to permit its being clamped by the respective clamping mechanisms, and act as a gauge to prevent the inter mediate portion of the beam resting on said support from being forced down below its proper position. Said support, while constituting a valuable feature of my invention, is not an indispensable element of the combination of the front and rear clamping mech anisms, since the heated beam may be held by other suitable means in proper position until clamped by the rear mechanism.

In the following claims, the expression beamsetting is to be understood as in eluding any analogous work to which the machine may be applied.
